We promise you the fast, professional calibration of your measuring instruments at the highest level. Depending on the type of device, we carry this out in our laboratory or at your premises.
Four advantages that speak in our favor
The regular calibration of your measuring equipment is of central importance if specified values are to be reliably maintained in critical processes. This also means a high level of responsibility for us – towards you.
All Mahr calibration laboratories work in accordance with ISO 17025. Depending on your requirements, calibration is performed at DAkkS level or at factory/ISO level. We document the results with audit-proof certificates. Through the International Laboratory Accreditation Cooperation ILAC, DAkkS certificates from Mahr are recognized worldwide.
More about this: Quality assurance & certificates
A whole range of factors guarantee that you will not have to do without your measuring instruments and standards for long: Standardized procedures and trained personnel ensure short throughput times and with the Mahr system boxes you can be sure of fast and professional transport to and from us. For very urgent cases we also offer quick calibrations of selected products.
Almost 160 years of experience in the development and manufacture of measuring technology also have an impact on our calibration services. Mahr's know-how ensures reliable, precise and reproducible results. As a pioneer in measurement technology, we have also helped develop many of the standards that apply today. So you can be sure: We know what we're doing!
Mahr is accredited for a wide range of dimensions in length and form metrology. We offer our services for all Mahr products as well as a wide range of handheld measuring instruments by other manufacturers. For you this means: Service from a single source, which reduces your administrative costs.
